Objectives: Doxorubicin is associated with a cumulative dose-dependent nonischemic cardiomyopathy. Cardiac magnetic resonance imaging (cMRI) is able to examine both structural and functional components of the myocardium. Our aim was to assess the myocardial changes in non-Hodgkin lymphoma patients undergoing doxorubicin-based chemotherapy using cMRI. Materials and Methods: cMRI examination was performed before and 3 months after chemotherapy. Experienced investigators interpreted each cMRI, and were blinded to all data. Left ventricular ejection fractions (LVEF), cardiac deformation, and delayed gadolinium enhancement (GD-DE) were quantified for each cMRI. The change between LVEF, GD-GE, and cardiac deformation parameters were compared between the 2 cMRI studies. A Δ LVEF≥10% was considered clinically relevant. The findings of GD-GE or changes in myocardial strain were analyzed as independent variables. Results: All 10 patients enrolled received a cumulative dose of doxorubicin of 300 mg/m 2. A comparison of pretreatment and posttreatment cMRI demonstrated 5 (50%) patients with a ≥10% decrease in LVEF (median, -8.4%; range, 1% to -17%; P=0.004). Three patients had at least 1 new or progressive segment of GD-DE. The global circumferential strain was significantly lower in patients after treatment, as compared with values before treatment (P=0.018) and to normal controls (P=0.046). Patients after treatment also had significantly lower global longitudinal strain than controls (P=0.035), and longitudinal strain values that tended to decrease compared with pretreatment values (P=0.073). Discussion: Our data suggests that cMRI has the ability to assess both early structural and functional myocardial changes in association with doxorubicin-based chemotherapy.
